Introduced in 1961 by Frank Drake, the Drake equation estimates the number of advanced alien civilizations in our galaxy. It focuses on factors like star formation rates, habitable planets, and the emergence of intelligent life. Since its inception, the equation has evolved with astronomical discoveries, questioning its relevance today amidst new knowledge about star variability, planetary habitability, and the search for biosignatures beyond traditional radio signals.
